PATENT EUGENE BEEBE, OF MILWVAUKEE, WVISCONSIN.

SPECIFICATION forming part of Letters Patent No. 412,013, dated October 1, 1889.

Application filed April 3,

To aZZ whom it new; concern:

Be it known that I, EUGENE XV. BEEBE, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Temperature-Regulators; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to devices for automat-ically regulating the supply of heated air or steam to a room or building, and will be fully described hereinafter.

In the drawings, Figure 1 is an elevation of my invention, showing all the connections; and Fig. 2 is a detail.

A A are the spools of electro-magnets.

B is an armature-lever, which is hung by a pivot 1) between the adjacent ends of the cores 0 a of the magnets, and to the lower end of this armature is hung a rod C, one end of which passes through the upper end of the vertical arm C1 of a bell-crank lever D and the other end through a similar vertical arm cl of a like bell-crank lever D. These bellcrank levers D and 1) are each formed with pivot-pins j, that are supported by brackets 0 that depend from arms 0 o of the frame of the apparatus, and the horizontal arm of each lever carries an adj ustable weight g.

The two arms 0 0 may be supported by the frame of my apparatus or by some portion of a furnace, and to one of these arms 0 is hung by wires or other suitable securing device (not shown) a pipe 71, that leads from a reservoir 11, containing water or compressed air, or other fluid under pressure, and this pipe has two branches, one of which it (which I term the supply branch) leads to an air or water chamber I, that is covered by a diaphragm or movable wall j, and has an arm 70, to which is pivoted a lever L, having a head L for contact with the movable wall, and connected at its free end by a cord or chain L with the dampers L L of the furnaces. The other branch 71- (which 1 term' the exhaust branch) of pipe h is supported by another arm 0' at a point opposite arm 0, and thence leads to the open air. \Vhile the pipe h and its branches maybe made of flexible material throughout the entire length, it is only necessary for the purposes of my invention to be 1888. Serial No. 269,427- (No model.)

flexible at points between the lines 00 a:that is, between the vertical arm (Z of leverD and arm 0 on one side and between the like arm of lever D and arm 0' on the otheran d normally both the pipe h and branch 71. are closed by the compression of the arms (Z (1 against the arms 0 0, caused by the weights g 9 described.

The ends of rod C slide loosely in arms (Z (Z, and the latter are held on rod 0 by nuts (2 d, that may be adjusted to draw arms (Z d toward each other or to permit them to separate.

M is the battery, which is connected to the spools of the magnets by wire M (though normally out of circuit therewith) and with the thermostat N by wire M and the two contact-screws O 0' of the thermostat are connected by wires P P with binding-posts P P respectively. Contact-springs p p are secured to the frame or furnace, each by apost p and one of these springs 13 extends under the contact-post P while the other overhangs post P (which contact-posts P P are insulated from each other,) and the end of the long arm of lever L projects in between the two springs and in position to strike either one of them and carry it away from its hinding-postwhen it is lifted or dropped by the diaphragm or movable wall j.

The operation of my device is as follows: As the parts are shown in Fig. 1 the front furnace-damper L or draft has been closed and the reniilating-damper L" opened and the room is being allowed to cool, and this continues until the temperature falls below the minimum for which the thermostat is set, with the battery entirely out of circuit. Now, when this occurs the thermostat N will be warped over to binding-screw 0, when the battery will be thrown in circuit through wire P, post P spring 1), wire Q, spool A, and. wire M back to battery, the current energizing the core of spool A, which, acting on armature-lever B, will draw it and rod C in the direction indicated by the arrow. The rod 0 by drawing on arm cl of lever D will overcome the resistance of weight g and draw said arm (Z away from pipe h, relieving it of compression and permitting water or air to flow from reservoir H to the air-chamber I, which, by pressure on the diaphragm j, will cause it to lift lever L, which, as it rises, will open damper L and permit damper L to close, and at the same time release spring 19, and then lift spring 19 out of contact, so as to cut out the battery, thus de-energizing the core of spool A and releasing the arm of lever D to permit its weight to press it against pipe 7t and close it, when the parts become station ary and will remain so until the thermostat again makes contact with screw 0, whereupon circuit will be made through Wire P, spring p, wire K, spool A, and wire M back to battery, energizing the core of spool A, which, attracting armature-lever B, will draw the arm cl of lever D out of contact with the branch 7L2 of pipe it, thus opening it to permit water or air to flow through it out of chamber I, which, as it empties, will permit the lever L to drop until it strikes spring 19 and breaks contact, when the core of spool A, being de-energized, will permit armature-lever B to resume a perpendicular, and the weight g of lever D will draw the arm (Z back to compress branch k and close it.

If found more convenient in any given case, there may be a separate armature-lever for each magnet, it being only essential that each of the magnets shall be located adjacent to an armature-lever.

In practice the weight got each lever D or D is so adjusted on the horizontal arm of its lever as to give to its vertical arm just suflicient pressure to enable it to tightly close the pipe adjacent to it when the magnets are de-energized and no more, and hence that magnet which is energized by change of temperature has no superfluous work to do and need not be as large as those generally required in regulating.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a temperat ure-regulator, of a reservoir containing water or fluid under pressure, a pipe leading therefrom having supply and exhaust branches, an armature-lever, and weighted levers connected thereto for keeping these pipes normally closed, an expansion-chamber connected to the supply branch and having a lever connected to the dampers of a furnace, a pair of magnets, each located adjacent to the armature-lever, and a battery wired to but normally out of circuit therewith, a thermostatwired to the battery, contact-points located on each side of the thermostat and wired to contact-posts adjacent to the lever on the expansion-chamber, and circuit making and breaking springs located adjacent to said contact-posts and wired to the said magnets.

2. The combination, in a temperature-regulator, of a reservoir containing water or fluid under pressure, a pipe leading therefrom having supply and exhaust branches, said pipe suspended from each end of said rod opposite the compressible points of the said pipe and branches, an expansion-chamber at the end of the supply branch, a lever pivoted to said chamber and having a head bearing against the movable wall thereof, and cords or chains at its free end connected to the dampers of a furnace, a thermostat wired to the battery, contact-points located on each side of the thermostat and wired to contactposts adjacent to the lever on the expansionchamber, and circuit making and breaking springs located adjacent to said contact-posts and wired to the said magnets.

3. The combination, with a reservoir and expansion-chamber, and a lever operated by the expansion-chamber and connected With a damper, of a flexible connection between said reservoir and expansion-chamber, and a flexible drain-pipe for said chamber, a thermostat and magnets wired thereto, a lever suspended between said magnets, and a lever connected with the armature-lever at one end and carrying an adjustable weight on its other end, and arms supporting the branches in position to be normally compressed by the bell-crank lever.

4. The combination, with the reservoir and expansion chamber and drain and supply pipe, of a thermostat and electro-magnet-s wired thereto, a swinging armature hung between the magnets, a pair of levers having weights on one end and connected with the armature-levers at their other end, and arms supporting the pipes in position to be compressed by the last-named levers, substantially as described.

5. The combination, in a heat-regulator, of a fluid-reservoir, a flexible pipe leading therefrom, an expansion-chamber connected with said reservoir by said flexible pipe, a lever connecting the expansionchamber with a damper or valve, a flexible drain-pipe leading from said expansion-chamber, levers adapted for compressing both flexible pipes, and a thermostat and electro-magnets in circuit, and an armature-leverconnected with the compressing-levers and controlling them, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
